While corruption exists everywhere, some countries have less tolerance for corruption than others. The US is not a very corrupt country, so assuming that money is all you need to bribe certain officials and get the info you are interested in is unwise. Also, while the Fed interest rates do have a certain impact on the stock market and perhaps a part of it correlates with the crypto market, let's not overestimate the impact. There are plenty of other important events, and I don't see the urgency of learning in advance what the Fed is going to do and when.
Some countries are rich already, though maybe you are right that there are still corruption that takes place on them and the corruption that happens there are not totally from the government but from a normal individual only. Some countries who have less tolerance for corruption are I think starts with their governments. Their governments can also be corrupt and are less strict when it comes to these things, so other people just copy this mannerism and they don't have a fear about this matter anymore for that said reason.
No one is ever under-estimating the FED or their rates because they are famous for having an impact in the financial market. We use them as one of the basis or check them before we do our crypto, stock, or other financial market activity, as it might help us to perform better.

But you once said that we must not overestimate the impact, remember? Indeed there are other events too but each of them should be given an importance as well and we here are speculating or predicting. We don't need to wait for things to happen first before we acted as there are no benefits anymore that we can get on them if we do.
